MANHATTAN BEACH, Calif., March 11, 2026 /PRNewswire/ -- K1 Investment Management, LLC ("K1"), one of the largest investors in small-cap AI-powered software, today officially announced its investment in Spin.AI, a security and data protection platform purpose-built to protect the cloud environments where modern enterprises run some of their most critical operations.

Spin.AI addresses a critical gap in enterprise security: many of the native tools embedded in today's most widely used platforms were not designed for the speed or sophistication of today's threat landscape. Ransomware, data leaks, misconfigurations, and third-party application risk can leave organizations exposed – and without the right platform in place, recovery from a breach could take weeks. The company's SpinOne platform helps unify SaaS security posture management, ransomware detection and response, data loss prevention, and backup and disaster recovery into a single AI-powered solution – delivering real-time visibility and an industry-leading 2-hour ransomware recovery service level agreement.

"At Spin.AI, our mission is to eliminate SaaS security risks before they become real-world breaches. The organizations we protect – from global enterprises to fast-growing technology companies – depend on us to keep their most critical SaaS data safe and recoverable," said Dmitry Dontov, Founder and CEO of Spin.AI. "K1 understands the urgency and complexity of securing modern SaaS environments and brings deep operational experience to help us scale. Together, we're working to redefine how organizations protect, manage, and recover their SaaS data."

"K1 seeks to partner with founder-led companies to build category-defining technology platforms," said Christian Grant, Principal at K1. "Many of the cloud platforms enterprises rely on were not built with today's threat environment in mind. Spin.AI has built the platform that helps close that gap – combining backup, ransomware response, posture management, and data loss prevention in a way that gives security teams real visibility and real control. That's the kind of mission-critical infrastructure we look to back."

K1 has partnered with security-focused companies across identity, email security, and data protection, including Axcient (sold to ConnectWise, backed by Thoma Bravo), Checkmarx (sold to Insight Partners and Hellman & Friedman), IRONSCALES, Pentera, and SecureAuth. As AI becomes more deeply embedded in enterprise operations, the platforms that protect and underpin mission-critical workflows move from operational necessity to strategic priority.
